Problem A (Ch 7 - Cross over Analysis-Cost ) The fixed cost (per year) and variable costs (per unit) for three potential processes are shown below. On the same chart (on graph paper) plot the Total Cost lincs for the three options. Use a whole page for chart. Use 18cm for maxx and 24cm for maxy. Show all relevant points on the graph and indicate the scale for each axis. Show clearly the calculations for scales (cm). Show and label all crossover points. Perform an analysis of the volume (state the range of output) over which each process is superior based on cost. Write down the range
